Welcome new followers! I’m interested in astronomy education and outreach, and count myself lucky to have a job managing @hausderastronomie.bsky.social and @astro4edu.bsky.social that allows me to follow that passion! I also post about politics, mostly related to climate change. 1/

Update: Der Bundesverband Wärmepumpe hat die Zahlen für 2025 jetzt auch mal aufgeschlüsselt. Sie kommen für die Wärmepumpen auf einen etwas höheren Wert als ich (aber die gleiche Größenordnung).

Any cuts to public education are devastating, but the loss of the department where I got my start really hits home.
Geoscience expertise empowers communities to effectively use resources and mitigate hazards. Nebraskans need and deserve that expertise, but it's being cruelly taken away.

They are really planning to go through with these cuts at Nebraska, despite recommendations not to. Unbelievable.
If you want to hire highly qualified, very successful earth and atmospheric sciences faculty in teaching and research, quite a few are probably looking for jobs for next year.

In the century leading up to 1975, nearly 6000 freighters went down in the Great Lakes.
The Edmund Fitzgerald was the last.
The last. In 50 years, not a single commercial freighter has been lost in the Great Lakes.
Why?
It's NOAA. Of course it's NOAA.

This is a point that cannot be made enough. (Feels like @olufemiotaiwo.bsky.social needs a tag here because I've re-skeeted his comments on how lying is so deeply corrosive a lot this year).
I agree. The narrative explanation for declining trust has become ‘political polarisation’ rather than ‘lying is now the norm’ which massively limits opportunities for adaptation and resilience to manipulation.

Für die #COP30 wurde ein Bus-Shuttleservice organisiert.
Die Busse fahren allerdings weite Routen und hängen im Verkehr fest, sodass man ewig braucht. Viele Teilnehmende nehmen deshalb lieber ein Uber. Was mehr Verkehr erzeugt, in dem dann alle festhängen.

This is exactly what’s wrong with Democratic Party leadership and why we need more people in Congress who will actually hold the line.

Pre-ACA, I was a postdoc on an NSF fellowship at a university that didn't offer employment benefits to independent fellows. At that time, being a woman meant that my premiums were double that of my male counterparts. The extra cost came out of my grant's budget for benefits, equipment, and travel.
